I know there is a Harley rental place not far from the airport.
Also my Uncle was given a rental when he had his BMW serviced. He used a BMW shop further away from the airport, cause thats where he lives.
Realistically thats all I would think to be available. I dont personally know of any other rental options but, I have never needed to do so.....
Best of luck dude, enjoy your travels
